PODataGridView SortCompare event doesn't fire
text
Body
copied!<p>Using VS2008, C# and .NET 3.5</p> <p>I am using databound DataGridView controls to display tabular data read from a web service. In several cases, there is a numeric column that needs to be sorted. I have tried a couple of different ways to get this to work, but the column still ends up sorting alphabetically (ie, 1, 10, 2, 3 instead of 1, 2, 3, 10).</p> <p>Setting the column data type to int doesn't work for databound controls, so the only real way to do this is to provide some custom sort logic.</p> <p>Many people have suggested hooking in to the SortCompare event to provide custom sort logic, but for some reason the event code never runs -- I can put a breakpoint in the handler and it never gets there. I am adding the event handler through the GUI, so the handler is added to the control by VS, not manually.</p> <p>Here's the event handler code, lifted from somewhere around here:</p> <pre><code> private void uxLicensedSoftwareDataGridView_SortCompare( object sender, DataGridViewSortCompareEventArgs e ) { int intValue1, intValue2; if ( !Int32.TryParse( e.CellValue1.ToString(), out intValue1 ) ) return; if ( !Int32.TryParse( e.CellValue2.ToString(), out intValue2 ) ) return; if ( intValue1 == intValue2 ) e.SortResult = 0; else if ( intValue1 < intValue2 ) e.SortResult = -1; else e.SortResult = 1; e.Handled = true; } </code></pre> <p>If this ever fired, it would do exactly what I want it to do. What could I be missing?</p> <p>Thanks for pointing out the (hopefully) obvious... Dave</p>
